The calibrator's switch test procedure
1. Once the switch test is started, the calibrator starts working towards
T
1
as quickly as possible. The calibrator's temperature changes
(heating or cooling) and switch status are shown in the display.
2. When T
1
is achieved and the temperature is stable, a "" is
displayed for one second.
3. The calibrator now starts working towards T
2
at the specified slope
rate.
4. In a normal situation, the thermostat changes state before T
2
is
achieved. If T
2
is achieved and the temperature is stable, "No Shift"
result is displayed.
5. When hysteresis is not selected (single temperature change), the
finished switch test result is displayed, see section 4.6.2.
When hysteresis is selected (two switch changes), the calibrator
starts working towards T
1
at the specified slope rate.
6. Normally, the thermostat changes state before T
1
is achieved. If T
1
is reached and the temperature is stable, "No Shift" result is
displayed.
7. The finished switch test results are displayed, see section 4.6.2.
4.6.2 Showing switch test results
Two types of switch test results are available:
Results during a switch test.
Results of a finished switch test.
